selftests: bpf: extend sub-register mode compilation to all bpf object files
At the moment, we only do extra sub-register mode compilation on bpf object
files used by "test_progs". These object files are really loaded and
executed.
This patch further extends sub-register mode compilation to all bpf object
files, even those without corresponding runtime tests. Because this could
help testing LLVM sub-register code-gen, kernel bpf selftest has much more
C testcases with reasonable size and complexity compared with LLVM
testsuite which only contains unit tests.
There were some file duplication inside BPF_OBJ_FILES_DUAL_COMPILE which
is removed now.
